The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move the summands with the other variables
from left part to right part, we given:
$$19 x = y + 4$$
Divide both parts of the equation by 19
We get the answer: x = 4/19 + y/19
19*x-1*y = 4
Looking for similar summands in the left part:
-y + 19*x = 4
Move the summands with the other variables
from left part to right part, we given:
$$19 x = y + 4$$
Divide both parts of the equation by 19
x = 4 + y / (19)
We get the answer: x = 4/19 + y/19

$$x_{1} = \frac{\operatorname{re}{\left(y\right)}}{19} + \frac{i \operatorname{im}{\left(y\right)}}{19} + \frac{4}{19}$$
x1 = re(y)/19 + i*im(y)/19 + 4/19
